SINK AND BASIN COCK.

SPECIFICATION forming part of Letters Patent No. 630,940, dated August 15, 1899.

Application filed Ie'brnary 17, 1899. Serial 110- 705,934. (No model.)

To all whom it may concern:

Be it known that I, HENRY SIEBEN, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Sink and Basin (Jocks, of which the following is a specification.

This invention relates to sink and basin cocks, and more especially to that class which close with the pressure of the fluid controlled.

The primary object of the invention is to provide a fixture of this character which will be relieved of the principal objection to the fixtures in common usenamely, the trouble and annoyance caused by the water escaping adjacent to the handle, sometimes with sufficient force to bespatter the adjacent wall and woodwork, as well as the person and apparel of the one manipulating the fixture.

A further object is to provide a fixture of this character having its valve-seat of such construction that it may be quickly and easily replaced with a new one.

A still further object is to produce a sink and basin cock which embodies simplicity, strength, durability, and cheapness 0f manufacture, combined with ornamental appearance and compact construction.

To these ends the invention consists in certain novel and peculiar features of construction and combinations of parts, as will be hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in -whioh Figure 1 is a central vertical section of a sink and basin cock embodying my invention. Fig. 2 is a horizontal section taken on the line II II of Fig. 1. Fig. 3 is a horizontal section taken on the line III III of Fig. 1.

In the said drawings, 1 designates the sink and basin cock, provided with a central chamber 2, from the upper end of which projects a discharge-spout The chamber 2 is provided with a central threaded opening 4: in its bottom and with a depending circular flange 5 externally screw threaded. 7 Above said chamber is formed the semispherical cup 6, provided with a circular shoulder 7 and a small cylindrical pocket 7, centrally perforated, as at 7".

8 designates the hollow base portion of the cock, screwed down upon the water-supply pipe 9.

10 designates a cylindrical ball-seat-, which is screwed into the threaded opening'4 and flares outward at its lower end, as at 11.

12 designates a semispherical hollow cover, which is screwed down upon the semispherical cup 6 and provided with a central open ing 13 and cam-surfaces 13".

13 designates a vertical rod which extends centrally through the perforation 7 and is provided at its lower end with cut-away portions 13", for a purpose which is hereinafter explained, and with a downwardly-disposed shoulder 15, formed by reducing the diameter of the rod from a point above the shoulder 7 to the lower end of the rod. It is also formed with a depending vertical stem 16 of smaller diameter than the rod, and mounted upon said stem is a resilient or rubber ball-valve 17, clamped up against the lower end of rod 13 by means of the washer 18 and clamping-nut 19. At its upper end the rod 13 is formed with a threaded portion 20 and a cylindrical pin 20", upon which is journaled the cam-collar 21, engaging the similar but opposing camsurfaces on the under side of the cover 12, said canrcollar being formed at the lower end of the stem 23, journaled in opening 13', and carrying the usual or any preferred type of valve-handle 24 in order that a person may conveniently and easily impart a twisting or turning movement to the stem 23,and thereby cause the vertical operation of the rodlS, the depression of said rod of course unseating said valve 17 by moving it downward. Upon releasing the handle the valve 17 is reseated by the pressure of the water against the lower end of the Valve, this action being facilitated and made more positive and reliable by the following mechanismthat is to say,by means of a practically-solid rubber ball 25, seated upon the shoulder 7 and occupying the spherical chamber formed by the cup 6 and cover 12, said ball being engaged at its upper side by the segmental cap 26, which is screwed upon the threaded portion 20 of the rod. This ball is provided with a tubular stem portion 27, fitting snugly in and down upon the bottom of the pocket 7, and with an internal shoulder28, engaged by the shoulder 15 of the rod, so that downward pressure upon the ball not only seats it tightly on the seat 7, but also, through the internal pressure applied by the shoulder 15, presses it tightly down into the bottom of the pocket 7 and outward against the wall thereof, so that it is absolutely impossible for water to enter the cup 6 from the chamber'below.

When the handle is grasped and the valve 17 unseated, as heretofore explained, the cutaway portions 13 of the rod 13 enter the cylindrical seat 10, and thereby leave alarger space for the passage of Water than would be provided if the rod were not reduced in diameter at this point. The depression of said valve, as explained, effectually prevents water from passing up into cup 6 and leaking over the cover 12a difficulty encountered in all sink and basin cooks now in use with which I am acquainted, this trouble occurin g largely by reason of the deterioration which in the course of time takes place in the rubber cushion employed to prevent the water from escaping at this point. I obviate this difficulty almost entirely by exposing to the action of the water a very circumscribed portion of the surface of the ball, this being accomplished by providing a perforation just large enough for the rod to pass freely through it. Furthermore, the ball is made exceedingly thick and heavy, and as such exposed surface gradually wears away the ball can be forced downward by screwing the cap'2'6 in the proper direction until such loss by wear is compensated for. When the operator releases the handle after unseating valve 17, the ball 25 expands and assists in the reelevation of the rod 13*, the relevation of the rod of course reseating the valve 17 and causing the handle to rotate back to its original position through the engagement of the cam-collar and cap.

If it is necessary at any time to replace the valve-seat cylinder 10 with a new one, it can easily be accomplished by unscrewing the upper part of the faucet from the base 8 and thenafter removing the ball 17 unscrewing the ball-seat cylinder 10. The parts are reassembled as easily. The procedure neces= sary to follow in removing and replacing the ball 25 is obvious and will be readily understood by reference to Fig. 1.

From the above description it will be ap parent that I have produced a sink and basin cock which embodies the features of advantage enumerated as desirable in the statement of invention, and it is to be understood that I reserve the right to make such changes as properly fall within its spirit and scope.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A sink and basin cock, comprising a chamber having a discharge-spout, a cup above the same, provided with a circular shoulder and a perforated pocket, a valve to provide for the entrance of water in the chamber, a rod carrying said valve and extending up through said perforated pocket, a ball upon said rod and seated upon said shoulder and in said pocket, a cap carried by said rod and resting upon the ball, and means to simultaneously depress said rod and said ball and thereby close communication between the chamber and the cup, and unseat said valve to admit water to said chamber, substantially as described.

2. A sink and basin cock, comprising a chamber provided with a discharge-spout and a valve-seat, a cup above the same formed with a shoulder and a perforated pocket, a rod extending through the perforated pocket and provided with a shoulder above the same and a valve below held by the water-pressure upon its seat, a ball-cushion mounted upon the rod and seated on the cup-shoulder and in the pocket and provided with an internal shoulder engaged by the rod, and means to simultaneously compress said ball upon its seat and unseat the valve, substantially as described.

In testimony whereof I affix my signature in the presence of two Witnesses.

HENRY SIEBEN.
